Easier Dunbar numbers

One thing I noticed while reading Liars and Outliers is that the Dunbar numbers Schneier estimates scale roughly with every other power of two. For me, this geometric sequence

Self, 2, 8, 32, 128, 512, 2048

is much easier to remember than the estimates Dunbar uses (which scale by three, roughly):

Self, 5, 15, 50, 150, 500, 1500

These represent estimates of the theoretical upper limits of human group sizes. Usually, your “clique” has 5 or fewer people in it. Your “sympathy group” has roughly 15 people in it, which probably includes your nuclear family and trusted friends. And so on:

Self, Self
5 (2), Clique
15 (8), Sympathy group
50 (32), Daily acquaintances
150 (128), Raiding party
500 (512), Megaband
1500 (2048), Tribe

Ad rem, this type of distribution gives rise to a more intricate and objective definition of introversion and extroversion*. An introvert prefers to invest more time with himself and the more intimate groups, whereas an extrovert invests significant time in maintaining relationships with people in the larger groups.

For instance, I could create an arbitrary definition by saying an introvert spends 80% of her time alone or with her clique.

*You know what? Fuck the alternative spelling with an A in it. Extraversion. That’s retarded and I won’t stand for it anymore!
